well think about it.
if you saw a dude wearing a skirt, high heels, and tank, would you think he was a weirdo?
and if you saw a girl in jeans, sneakers, and a t shirt, would you think she's a weirdo?
i think that answers your question.

I mean obviously there are some things that you don't want to see guys wear, but I can't see that being a valid argument because they can dress equally disgusting without cross-dressing, and there is plenty of cross-dressing that wouldn't be disgusting like that.

because it's very awkward to see guy wear skirt coz... most of them have hairy leg and have a muscle so maybe it's very uncomfortable to see it
well or maybe sometimes girls got jealous when pretty guy wear skirt or long dress and they look pretty than girl
well, it's just awkward see guy wear girl stuff coz they are very gentle and manly so they prefer wear jeans and t-shirt or shirt
for me... I prefer wear jeans or short and T-shirt coz it make me comfortable and free, I can't be myself when I wear skirt it's just very awkward to me
